Abstract

Abstract. Scots pine is a widespread plant on the territory of the Russian Federation. Scots pine cones are thought of as an advanced raw material for the research of the chemical composition and pharmacological activity. The object of this paper was the research of the essential oil component composition and antioxidative activity of young Scots pine cones collected in the Perm region. The samples of Scots pine cones were collected in the Yurlinsky, Ilyinsky, Permsky and Bardymsky districts of the Perm Region for the essential oil component composition research. The essential oil component composition was determined by the gas chromatograph with a mass selective detector Agilent 7890A. The antioxidative activity of raw materials infusions was determined by their ability to bind the free radical 2,2-diphenyl-1-picrylhydrazyl. As a result of the research, 10 components related to monoterpenes and sesquiterpenes were identified in the essential oil of Scots pine cones of all regions. The monoterpene fraction predominates in the essential oil of Scots pine cones in all districts of the research. The content of sesquiterpenes slightly increases in the essential oil of the more southern districts of the region, such as Permsky and Bardymsky. The content of sesquiterpenes in the essential oil of more southern districts grows mainly due to an increase of caryophyllene and humulene. The main component of Scots pine cones essential oil is the dicyclic monoterpene α-pinene. Basing on the results of the antioxidative activity determination, it was found that the infusions prepared from young pine cones collected in the Ilyinsky, Bardymsky and Permsky districts have the maximal ability to bind free radicals. The infusion of the pine cones from the Yurlinsky district has showed the least antioxidative activity, which can be ascribed to a high content of the monoterpene fraction in the essential oil.
